超低频地震电磁现象及前兆信息检验评估
ULF seismo-electromagnetic phenomena and evaluation of precursory information
摘要
Abstract
Extensive laboratory experiments and field observations have confirmed the existence of ultra-low-frequency(ULF)electromagnetic phenomena related to seismic activity.However,due to th weak and disturbance-prone nature of these signals,the reliable identification and extraction of earthquake-related electromagnetic anomalies remain technically challenging.Moreover,translating such electromagnetic data into practical applications for disaster prevention and mitigation remains a pressing issue.This study provides a comprehensive review of recent advances in ULF electromagnetic research related to earthquakes,critically examines the existing challenges and limitations,and explores key priorities and future directions.It is intended to stimulate further research and offer valuable insights for the development of this field.We begin by briefly introducing the phenomenon of earthquake-related electromagnetic signals.Then,we summarize recent developments in ULF electromagnetic research related to earthquakes,present several representative seismic cases and data analysis methods,and highlight statistical findings obtained from long-term observations at the earthquake electromagnetic experimental site near Tokyo,Japan.Following this,we detail the methodologies used to evaluate the precursor information contained in electromagnetic signals and briefly discuss their possible physical mechanisms.Finally,we identify the key challenges that remain in current earthquake electromagnetic research and outline potential directions for future studies.关键词
